A written refund request must include your name, contact information, the amount, account or order number, a clear explanation of the problem, and copies of supporting documents. The specific details you need to include depend on whether you're requesting a refund directly from a medical provider (merchant refund), disputing a charge through your credit card company under the Fair Credit Billing Act, or filing a chargeback—each has different legal requirements. For medical billing refund requests, you may be addressing an overpayment, a charge you don't recognize, or an error on your statement. Understanding which type of request you're making helps you include the right information and send it to the right place.

Components for a Standard Refund Request
According to the Federal Trade Commission, a written refund request to a hospital or provider should include your full name and return address; your contact information (phone and email); the business name and department handling refunds; a description of the service or procedure you were charged for; the date of service; the amount of the charge; your account or order number; a detailed explanation of why you're requesting a refund; evidence of previous attempts to resolve it (such as prior calls or letters); the refund method you want (original card, check, account credit); and supporting documents like your explanation of benefits, invoice, receipt, or proof of payment. Providing all this information makes it difficult for a provider to dismiss your request or claim they didn't understand what you wanted.
If You Paid by Credit Card (FCBA Requirements)
If you used a credit card and believe the charge is an error, the Fair Credit billing Act provides specific protections. Your written dispute must include your name, account number, the error amount, and a clear explanation of why you believe the charge is incorrect. The creditor must acknowledge your dispute within 30 days and resolve it within two complete billing cycles—up to 90 days. Critically, your written notice must be sent via mail (not email or phone) to the billing inquiries address, and it must be postmarked within 60 days of the statement showing the error. Missing this deadline means you lose federal billing-dispute protections.
How to Send It and What to Keep
The Federal Trade Commission recommends sending written refund requests via certified mail with return receipt requested. Keep copies of your letter, all supporting documents, receipts, invoices, and any previous communications with the provider or creditor. For FCBA billing disputes, the sending method is legally significant—your written letter by mail is what triggers the creditor's mandatory 30- and 90-day obligations. A documented paper trail protects you if the provider or creditor claims they never received your request or if you need to escalate to a chargeback dispute later.
Deadlines You Must Know
According to the Federal Trade Commission, merchants are required to refund credit card purchases within seven working days. The format of your written refund request itself has no legal requirement beyond what the merchant's return policy specifies. For credit card billing disputes under the FCBA, the 60-day postmark deadline is mandatory—you must mail your letter by that date to preserve your federal rights. If you miss the 60-day deadline for an FCBA dispute, you lose the creditor's mandatory acknowledgment and 90-day resolution timeline and will need to pursue a chargeback instead.
When You Might File a Chargeback Instead
If your FCBA dispute doesn't resolve within the timeline or if the creditor fails to acknowledge it, you can file a chargeback with your credit card company. According to Mastercard's chargeback guide, chargeback disputes require category-specific documentation: for goods you may need proof of delivery, for services you may need service records, and for recurring charges you canceled you may need cancellation proof.
The documentation must be legible and directly address your specific allegation. A chargeback is a separate path with its own timeline and rules—not a replacement for an FCBA dispute, but an option when that route doesn't work.
Frequently Asked Questions
What if I didn't keep my receipt or explanation of benefits?
Gather whatever documentation you have—payment records, emails confirming the charge, correspondence with the provider, or statements. Submit what you have along with a clear explanation of the error. The more detail you provide about why you believe the charge is wrong, the stronger your case.
Can I send a refund request by email instead of certified mail?
For regular merchant refunds, email may work depending on the provider's return policy. However, for credit card billing disputes under the FCBA, your written notice must be sent via mail (not email) to preserve your federal protections and trigger the creditor's 30- and 90-day legal obligations.
What happens if the provider doesn't respond to my written request?
If you sent your letter via certified mail with return receipt, you have proof of delivery. For credit card disputes, if the creditor doesn't acknowledge your claim within 30 days, that's a violation of the FCBA and you can escalate to your state's attorney general or file a chargeback with your card issuer.
